Totally normal! The uterus is doing a big stretch around 9 weeks and a lot of women begin getting cramps. As long as they aren't unbearable or combined with bleeding, drink lots of water and rest as much as you can. :-)
I had the same sort of pain at your stage of labour and it was normal due to all the stretching and body adjustment that the body goes through. I got them checked out cause even though this is my second pregnancy and I didn't experience it in my first.
A little cramping is normal... after all your uterus is stretching and growing to make room for your wee one. If the pain gets too intense or seems excessive you can alwaysvcontact your obgyn and discuss it with them. Congrats on the pregnancy!
